I am a scuba diver and log every dive. Is it a good idea to log all your shots and if so is there a free gun log I can download?
If your doing a simple range session (100yds) I would just log the amount of rounds fired and your weather conditions. If your doing load data, write down the load weight, bullet used, powder, primer, and brass. You also want to record seating depth. Make sure you log whether you cleaned between groups, or shot from a dirty bore and how many shots are made in each test. I like to keep track of the group size too.
In all instances of shooting you want to log your cold bore shot (first shot on a dirty barrel or clean barrel) and track whether it shoots with the following shots, or if it has a tendency to have a separate point of impact away from the following shots.
When shooting long range, you want to log each shot, drops required for the range you are shooting, wind conditions, temp, barometric pressure, humidity, and elevation. Temperature, wind, and drops are the most important.
